The adjustable curtain rods for window treatments measure between 21 inches to 60 inches with a half inch diameter. Perfect for a living room, bedroom or den area that needs a well built curtain rod. Great for decorative short window treatments in the kitchen or bedroom that need a shorter length to fit the wall. The popular size for extra long curtain rods measure around 61 inches. Since these short to medium iron curtain rods are adjustable, you can slide the rods over each other for the desired length. To support the middle of the iron curtain rods, we suggest to install a center support bracket that is included with the hardware. This will support the weight of the draped curtain rod and keep them from bending. Decorating with these durable curtain rods are beneficial in that they are sturdy, well made curtain rods that are strong. There are many styles to choose from such as the Acorn Leaf, Hummingbird, Victorian Key or Fleur-De-Lis curtain rods.
